Ich habe ein Stück Code mit try-catch-Block:Junit mit Ausnahme
public static void writeExcelToFile(String outFileName, HSSFWorkbook workBook) throws IOException{
File file = null;
FileOutputStream fileOutputStream = null;
try {
file = getFileByFileName(outFileName);
File parent = file.getParentFile();
Path filePath = parent.toPath();
if (Files.notExists(filePath) && !parent.mkdirs()) {
throw new IOException("Couldn't create dir: " + parent);
}
fileOutputStream = new FileOutputStream(file);
workBook.write(fileOutputStream);
} catch (FileNotFoundException fileNotFoundException) {
LOGGER.error("File path is invalid, file not found ", fileNotFoundException);
throw fileNotFoundException;
} catch (IOException ioException) {
LOGGER.error("Exception occured while reading writing file ", ioException);
throw ioException;
} catch (Exception exception) {
LOGGER.error("Exception occured ", exception);
throw exception;
} finally {
if (fileOutputStream != null) {
fileOutputStream.close();
}
}
file.setWritable(true);
}
ich folgende Junit für den Fang Block geschrieben haben:
//#1: FileNotFoundException
@Test(expected = java.io.FileNotFoundException.class)
public void testWriteExcelToFileException() throws IOException {
PowerMockito.mockStatic(KnewtonCIExcelWriter.class);
PowerMockito.doThrow(new java.io.FileNotFoundException()).when(KnewtonCIExcelWriter.class);
KnewtonCIExcelWriter.writeExcelToFile(anyString(), anyObject());
}
//#2: IOException
@Test(expected = IOException.class)
public void testWriteExcelIOException() throws IOException {
PowerMockito.mockStatic(KnewtonCIExcelWriter.class);
PowerMockito.doThrow(new IOException()).when(KnewtonCIExcelWriter.class);
KnewtonCIExcelWriter.writeExcelToFile(anyString(), anyObject());
}
//#3: Exception
@Test(expected = Exception.class)
public void testWriteExcelException() throws IOException {
PowerMockito.mockStatic(KnewtonCIExcelWriter.class);
PowerMockito.doThrow(new Exception()).when(KnewtonCIExcelWriter.class);
KnewtonCIExcelWriter.writeExcelToFile(anyString(), anyObject());
}
jedoch nur die letzte, # 3 Junit vergeht. # 1 und # 2 gibt java.lang.AssertionError: Erwartete Ausnahme: java.io.FileNotFoundException und java.lang.AssertionError: Erwartete Ausnahme: java.io.IOEXception.
Question: 1) How to get the #1 and #2 JUnit passing? 2) Am I catching the correct exceptions?
Bitte PowerMock Dokumentation lesen, 'PowerMockito.doThrow (new Exception()), wenn (KnewtonCIExcelWriter.class).' Dies fehlt ein Funktionsnamen –
